No I wouldn't want to use it all the time, when I did, I was proving a point to a friend of mine that said you couldn't use an entry level digital camera to shoot sports. Shooting football is something that I am very good at, but then I have been shooting it for over 40 years and also understand everything about the game. So many people are being told on this forum that sports can't be shot with entry level digital cameras, or even a mid-range digital, and that is bs. There is a challenge when using a camera that doesn't follow focus very well and people get frustrated and disappointed when they don't end up with the photos they want. They feel defeated by the technology and give up, which is the wrong attitude.
Anything is possible in time, but in this day and age, people want everything fast, great photos don't happen fast. I always hope that people continue on with photography, regardless of what people say about what is and isn't possible.
I'm not that "up on" lower-end Canon bodies...but the thing is, a 300mm f/2.8 Canon or Nikon with its own, custom-designed ultrasonic focusing motor is one of the best-focusing, best-performing lenses made. All of the modern AF super-teles focus fast, and they focus surely. I've used the old Nikon D70 with its crude, 5-point autofocus system with my 300/2.8, and it focuses FAST, and surely...even with a very low end, outdated body and AF system.
Back in 2005, I wanted to try the 300/2.8 on my D70, so I tried about 40 frames with it at this soccer game. I'm not really a sports shooter fanatic, but I was impressed with how fast a 300/2.8 is at focusing, compared against slower lenses or slower zooms. The D70 is a sloooow camera, 3 frames per second, so you have to pick the right time to hit the button. I only shot parts of TWO events with the D70; this afternoon soccer match in October, and this rainy day track meet. I was shooting the D2x that year for pretty much everything, but I did want to see how much was "the camera", and how much was "
the lens" (300/2.8 AF-S II, the magnesium barreled lighteight model).
Only took one shot.
Only get one frame, of the plant of the pole..by the time the D70 is ready to fire a second frame, the vaulters are already over the bar..or not...
Not that these are great shots, but a 300/2.8 focuses so fast, and so surely, compared to a consumer zoom lens. I think that's the real issue...people often say such and such camera focuses slowly; well...maybe with an 18-200mm f/3.5~5.6 lens it does, but with a FAST pro-grade telephoto lens, "in" and "out" of focus are soooo different that phase detect AF systems get good,good data, and can focus VERY fast. The same is NOT true with short lenses, where the image is sort of in-focus all the time, and the AF system see-saws back and forth, back and forth.
I dunno; what lens makes a 6D focus slowly??? I have a sneaking feeling that with say, a 70-200 Canon or even their 200/2.8, OR with my fave Canon lens, the 135/2-L, that the 6D will lock focus on HS football like a demon. Maybe I am wrong, but I think it's likely that the right LENS will make the 6D capable enough for HS football. The jerseys have a great big, high-contrast AF target right on the front and back...
